Abstract
The utility model discloses a center draft tube, including the center draft tube body, inlet tube and toper reflecting plate, the center draft tube body is a vertical cylindrical barrel, center draft tube body bottom is equipped with a horn mouth no. 1, the toper reflecting plate is located horn mouth no. 1 under, toper reflecting plate and horn mouth are equipped with the band iron support between one, the lower part on the center draft tube body face of cylinder is connected to the inlet tube tangential, it serves and is equipped with a return bend to lie in center draft tube body inside on the inlet tube, the return bend opening is vertical upwards, the open end of return bend still is equipped with a horn mouth no. 2, the inside return bend below that is located of center draft tube body is equipped with a screw -tupe fin. Not only can effectively cushion the release of the energy of intaking, effective controlled flow rate reduces the impact force, can make the sedimentation tank in the suspension material effectively subside, and the aerobic bacteria who gets rid of the aquatic that can be fine can let get into the sedimentation tank bottom behind the flocculating agent complete reaction of aquatic simultaneously, reaches fine sediment effect.
Description
Technical field
The utility model relates to a kind of central draft tube, belongs to technical field of sewage treatment equipment.
Background technology
Traditional sedimentation basin central draft tube comprises central draft tube body and at least one water inlet pipe, a horn mouth is provided with below central draft tube body, reflecting plate is provided with below horn mouth, water inlet pipe is arranged on the top of central draft tube body, in reaction tank, water out directly flows to below by Action of Gravity Field above central draft tube body, then gets to reflecting plate enters bottom sedimentation basin to precipitate.Although structure is simple, but owing to entering the intrinsic water of central draft tube by water pump lifting, directly pour bottom sedimentation basin, not only energy is higher, and water velocity is excessive, impulsive force is also larger, suspended material in sedimentation basin can be caused not settle down on the one hand, the mud be deposited in bottom sedimentation basin can be broken up simultaneously, badly influence the sedimentation effect of sedimentation basin, and easily reflecting plate is caused damage, on the other hand due in water out from reaction tank containing flocculant, and this flocculant does not also have complete reaction, if be directly punched into fast bottom sedimentation basin, sedimentation effect can be had a strong impact on, moreover due to flow velocity too fast, also the aerobic bacteria in water cannot well be removed.So at present water inlet pipe to be tangentially connected to the bottom on the central draft tube body face of cylinder, it is made tangentially to intake, thus effectively cushion the release of water inlet energy, reduce the impulsive force bottom sedimentation basin, reduce the impact of inflow fluctuation on sedimentation basin cloth water flow field, mud bottom sedimentation basin can not be broken up, and the infringement reduced reflecting plate, but because water inlet pipe is a straight tube, inflow control is carried out again without other components, therefore flow velocity or uncontrollable, also just well cannot remove the aerobic bacteria in water and cannot allow flocculant complete reaction, sedimentation effect is also waited to improve.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined is to provide a kind of rational in infrastructure, central draft tube that cost is low, effectively can not only cushion the release of water inlet energy, effective coutroi velocity, reduce impulsive force, suspended material in sedimentation basin can be made effectively to settle down, and well can remove the aerobic bacteria in water, can allow after the flocculant complete reaction in water enters bottom sedimentation basin simultaneously, reaches good sedimentation effect.
For achieving the above object, the utility model is by the following technical solutions: a kind of central draft tube, comprise central draft tube body, water inlet pipe and taper reflecting plate, described central draft tube body is a vertical cylindrical tube, described central draft tube body bottom portion is provided with a horn mouth one, described taper reflecting plate is positioned at immediately below described horn mouth one, band iron support is provided with between described taper reflecting plate and described horn mouth one, described water inlet pipe is tangentially connected to the bottom on the described central draft tube body face of cylinder, the one end described water inlet pipe being positioned at described central draft tube body interior is provided with a bend pipe, described bend pipe opening straight up, the openend of described bend pipe is also provided with a horn mouth two, described central draft tube body interior is positioned at below described bend pipe and is provided with a spiral fins, described spiral fins is fixed on the inwall of described central draft tube body, and the center line of the center line of described spiral fins and described central draft tube body on the same line.
As preferably, the material of described spiral fins is galvanized steel plain sheet or stainless steel.
Effective achievement of the present utility model: the utility model is rational in infrastructure, cost is low, water inlet pipe is tangentially connected to the bottom on the central draft tube body face of cylinder, and carried out structural design in water inlet pipe one end, add opening bend pipe straight up and horn mouth two, and added spiral fins in central draft tube body interior, water is made to have bottom rhythm sequential slowly inflow sedimentation basin, effectively can not only cushion the release of water inlet energy, effective coutroi velocity, reduce impulsive force, suspended material in sedimentation basin can be made effectively to settle down, and the aerobic bacteria can well removed in water, can allow after the flocculant complete reaction in water enters bottom sedimentation basin simultaneously, reach good sedimentation effect.
